This invention relates to liquid dispensing apparatus and is particularly directed to the provision of means associated with a tank enclosing structure or casing whereby lany one of several grades of lubricating oil contained in respective Another object of the invention is the provision of means whereby oil from any one of several compartments included in a unitary structure may be directed through a respective conduit to a compartment in which a measured quantity' of the oil (as for example a. quart) is visibly indicated and therefrom delivered through a hose directly to a motor.

Another object of the invention is the provision of motor driven valve actuating mechanism associated with means operable to automatically stop the motor when a valve has been opened for a predetermined period. a

Another object of the invention is the provision of a selector element movable into operative opening relation between any one of several Y valves and respective motor driven elements, each valve controlling iiow of a different grade of oil.

With the above and other objects in view, as will hereinafter appear, the invention comprises devices, combinations and arrangements of p arts set forth in the Afollowing detailed description and illustrated in the accompanying drawings of one form of embodiment of the invention, from which characteristics of the invention and the advantages attained thereby will he readily understood. It will further be understood that the invention is not limited to the exact form and arrangement shown and described but maybe varied in many respects without departure from the scope of the invention as defined by the. appended l claims.

Figure 4 is a detail view of a portion of the rear of the casing.

Figure 5 is a detail sectional view of a conduit and valve.

vReferring to the drawings the oilv dispensing structure illustrated includes a base plate I which provides suitable support for mechanism enclosedv by sheet metal sides 2 of casing 3 which is provided witha top closure d. The latter may be 'surmounted with glass globe 5 to provide orna- 'mentationfand an enclosure for light bulbs as Well as an areafor advertising matter.

Several tank compartments as 6, 1 and 8 are supportedin the upper part of the casing for containing supply of various grades of oil such as may here be indicated respectively by A, B and'C. From each supply tank a conduit as 9 leads to a measuring compartment Ii supported on the front of the casing together with a transparent' insert I2 which provides for visible indication of the amount of oil contained by the compartment, such as a quart, the usual unit of measurment used for saleV of motor oil. For delivery of this measured quantity, as directly to the motor of an automobile, a hose ld is provided leading from the bottom of the compartment il through an opening I5 in casing 3. Each conduit 9 is provided with a respective valve I6 for i controlling flow of oil from respective supply tanks to the measuring compartment il.

Means for selectively connecting mechanism f for opening any one of the several valves I6 with a source of power for a period suicient to fill the measuring compartment will now be described. Such a source of power may comprise the motor Il for driving shaft I8 through a reducing gear unit I9 ata comparatively slow rate of speed. Shaft I8 supported at one end by gear unit I9 may be further supported at its other end in journal 20 of standard 2i. Also supported by the gear unit and standard are rods 22, 23 and 24 extending in parallelism With shaft I8 for a purpose that will presently appear. Keyed to. shaft I8 are several. cams as 25 corresponding in number and respectively oppositely disposed to valves I6,`while interposed between each cam and valve is a lever 26 freely mounted for oscillatory movement on rod 22. Each lever 26 consists `of a slotted arm 2l and an arm 28, the latter being opposed to its respective cam 25 but separated therefrom so that the cam has no effect thereon unless suitable means are intery posed between it and said arm 28. Such means may comprise an arm 29 supported for oscillatory movement on rod 23 and also movable longitudinally of the -rod so that it.may be intel'DOsed between any one of the cams 25 and its respective cooperating lever arm 28. Arm 29 is provided atits outer end with an antifriction roll 30 for contact with the aforesaid elements between which it is adapted to be interposed. For manually shifting arm 29 into operative relation tain arm 29 in such elevated position that it can be moved into position to cooperate with cams 25, rod 24 acts ,as a stop to limit its downward drop when it is moved from one cam to another.

From the foregoing it will be clear that any one of levers 26 may be made to oscillate on its support through the effect of its respective cam 25. To transfer the effect of such oscillation to a respective valve I6, arm 21 of each lever is connected to the respective movable valve element 31 by a rod 38 which is pivoted at 39 to valve stem which is extended through stuffing bo'x 4I.

To normally hold the movable valve element 31 in closed position, a spring 42 is opposed thereto'by with any one of the several cams 25, a selector ton 48 to stop the motor. During this period of motor operation the valve for controlling ilow of oil from tank compartment 6. has been open just long enough to till visible measuring compartment II and this measured quantity may next be delivered directly to a motor through deliveryl neath the tanks and connected with a source of current which may be applied in different degree by a high-low switch as v52.

Having thus described my invention, what I claim is:-

l. Liquid dispensing apparatus including in` combination,l a liquid storage compartment. a

4liquid measuring compartment, a conduit connecting the compartments, a normally closed` valve in the conduit, a driven shaft, a cam on the shaft, a rock lever supported adjacent the cam, means for connecting one arm of the lever with the valve, and movably supported means adapted to be interposed between the other arm of the lever and the cam to render -the cam effective to actuate the rock lever to open the valve.

2. Liquid dispensing apparatus including in combination, a. liquid storage compartment, a liquid measuring compartment, a conduit connecting the compartments, a valve in the conduit, a spring for normally closing ,the valve, a driven shaft, a cam on the shaft, a rock lever supported a shouldered member 43 threaded into the valve` adjacent'the cam, a connecting member pivotally wall at 44, This member also acts as .a guide to valve stem45 which is surrounded by the spring.

As above stated cam shaft I1 rotates at a low rate of speed. It is so timed that one revolution of a cam may cooperate with the interposed means described, to hold a valveopen for an interval just sufficient to permit the desired vmeasured quantity of liquid to flow from a respective supply tank to the visibly measuring -compartment I I. For exactly controlling this lilow under diierent conditions, such as change in temperature and variation in fluidity, means are provided whereby the amount of valve openjing eiected by action of a cam may be changed. 'Ifo serve this purpose, adjustment of the connection between lever arm 21 and valve actuating rod 38 is permitted by the slot 29', that ls to say, the effective throw of the arm 21 may be varied so as to hold the valve open a greater or lesser amount for the given period of valve opening determined by duration of rotation of the cam.

Means for control of the motor I 6 may comprise a s nap switch as 46 having exterior to casing 3 Q a button 41 for manipulation to start the motor -Lfgand'a button 48 inside the casing which may be jc'am operated to stop the motor. Such a cam 49 having a short button-actuating lug5IJ is secured to shaft I1 and is so arranged that it will throw the switch to stop the motor after the cam shaft has made one revolution.

Assuming that a quart of grade A oil is to be delivered from the tank structure, the method of proceedure is as follows: First selector handle 32 is v moved along slot 35 until it drops into notch 36 which is marked Grade A. Then -the snap switch button 41 is pressed in to start motor I1,

which after one revolution of'the cam shaft I8 is stopped by cam lug 5|) which actuates switch'butassociated with one arm of the rock lever and with the valve, means for permitting adjustment of the pivotal lever connectionV of the connectments, a liquid measuring-compartment, a conduit connecting each Astorage compartment with thev measuring compartment, a normally closed valve in each conduit, means including a rock. lever associated with each valve, a driven shaft, a cam on the shaft adjacent each rock lever, and movvably supported means adapted to be interposed between any one of the camsand its rock lever` to render the cam effective to actuate the-lever.V

and open its respective valve.'
